A fishing line is being manufactured by two processes. To determine if there is a difference in the mean breaking strength of the lines, 10 pieces manufactured by each process are selected and then tested for breaking strength. The results are as follows: Process 1 10.4 9.8 11.5 10.0 9.9 9.6 10.9 11.8 9.3 10.7 Process 2 8.7 11.2 9.5 11.0 9.8 9.8 10.1 10.8 10.5 9.9
